POULTRY-BROODER.

Specification of Letters Patent.

Patented May '7, 1907.

Application led August 15, 1906. Serial No. 330,642.

To all whom, t may concern:

. Be it known that I, HENRY H. DAMMAN, a citizen of the United States, residing at Kiowa, in the county of Barber and State of Kansas, have invented new and useful Improvements in Poultry-Brooders, of which the following is a specification.

This invention relates to brooders, and the primary object of the same is to provide a device of this class having a simple and effective heating organization which operates to maintain a regular degree of heat within the body of the brooder and also to maintain the proper moisture within the latter. The heating organization includes a central drum with a surrounding shield and radial pipes communicating with the interior and penetrating the top of the. drum and also having a conduit extending outwardly within the upper part of the brooder to convey the heat at a distance from the drum and nearer the sides and ends.

The improved brooder also embodies ventilating slides as well as a controlling slide which is operative to permit the heat from the prime heating generator either to pass directly into the drum or caused to be radiated from the regulator and pass into the drum in accordance with the degree of heat necessary for the chickens.

The improved brooder also includes other details of construction which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a side elevation of a brooder embodying the features of the invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a horizontal section through the upper part thereof.

Similar numerals refer to like parts throughout the several views.

The numeral 1 designates an inclosing frame having a hinged top 2 and supporting legs 3. At opposite sides', openings 4 are provided near the bottom of the inclosing frame or casing and are normally covered by transparent slides 5. The openings 4 provide means for gaining access to the interior of the brooder and also for permitting the chickens to pass out onto ledges or supports 6 adjacent to the said openings and having surrounding guards or flanges 7. The ledges 6 with their guards or flanges provide means for feeding the chickens and also serve Vas limited runs for airing purposes. At the top of the front and rear sides ofthe frame or casing 1 ventilating openings 8 are formed and are normally covered by drop slides 9.

In the center of the bottom 10 of the inclosing frame or casing an opening 11 is formed and fitted thereover is a heating drum 12 which is imperforate but fully open at its lower end. A metal supplemental bottom 13 is held by the frame or casing below the bottom 10 and has a central opening 14 therein immediately below the opening 11 and drum 12, the opening 14 having an imperforate slide 15 cooperating therewith for a purpose which will be presently set forth. Below the supplemental bottom 13 a lamp hanger 16 is secured to the frame or casing and is of such construction and arrangement that a lamp 17 may be readily disposed therein. The lower portion of one end of the frame or casing has an opening 18 formed therein which is covered by a slide 19. The purpose of this opening is to provide means for permitting the lamp 17 to be reached and seen from one end of the brooder in placing and removing said lamp. The slide 19 is readily movable, but when closed it excludes all draft or other detrimental air influence with respect to the lamp 17. Near the opening 18 is a draft opening 2O which is normally closed by a slide 21 which is clearly'shown by Fi 3.

Surrounding the drum 12 is a metal shield 22 which prevents the chickens within the brooder from coming in direct contact with the highly heated drum. On top of the drum 12 a water pan 23 is secured and readily accessible through the top of the brooder and will be supplied from time to time with water to maintain a suitable moisture within the inclosure provided by the frame 1. Radially extending through the upper part of the brooder and penetrating the top of the drum are pipes 24 which operate to carry off the products of combustion or smoke from the lamp and also to heat the portions of the brooder through which they extend, said pipes 24 communicating with the exterior of the brooder. A circular heat conveying conduit or pipe 25 is disposed on the pipes 24 and has one extremity radially projecting inwardly as at 26 and penetrating the top portion of the drum. The opposite extremity27 of this circular pipe 25 passes through one side of the casing or frame 1 and serves as an outlet. This circular pipe also receives the products of combustion and heat currents from the frame and conveys them around the upper part of the brooder at a desired distance from the pipes 24 and by this means the up- IIO per part of the brooder is thoroughly heated at a distance from the drum.

When the lamp 17 has been placed in the hanger and lighted, the heat therefrom, if the slide 15 is open, will pass directly upwardly into the drum 12,'in a strong current and thoroughly heat the interior of the brooder. The heat from the drum 12 passes out through the pipes 24 and 25 and the upper part ofthe brooder at a distance from the drum is thus thoroughly heated, the chickens being permitted to group or freely move about the lower portion of the drum at a distance below the pipes and withoutliability of injury from the highly heated drum, in view of the protection provided by the shields 22. If as great a degree of heat is not required as when the opening 141 is clear, the slide 15 is closed and the heat from the lamp is radiated from said slide and passes into the drum. Another point is that the supplemental bottom 13 being of metal and forming a cham-' ber with the bottom 10, the heat from the metal is radiated in said chamber and materially affects the said bottom 10. At any time desired the brooder may be ventilated to lower the temperature, particularly when it is found that the degree of heat is too great.

The brooder may be cheaply manufactured and in view of its simplicity is'readily operated. It will be understood that the inclosing frame will be made of suitable wood and the drum 12 and shield 22 as well as the pipes 211 and 25 may be of any preferred metal. The brooder may be made as large as desired or its capacity varied in accordance with the demands of the user.

wWhat I claim is:

1. A brooder comprising an inclosing casing with an opening through the bottom thereof, a drum secured on the bottom, a prime heat generating means held below the drum, the latter having an imperforate structure, pipe communicating with the upper part of the drum and the exterior of the brooder, a portion of the pipes being radially disposed and the remaining part circularly arranged, and a water pan held on the top of the drum.

2. A brooder comprising an inclosing casing with an opening in the bottom thereof, a supplemental bottom below the main bottom having an opening therein, a slide movably cooperating with the supplemental bottom, a prime heat generating means below extending upwardly into the brooder and coinciding at its lower extremity with the main bottom, pipes communicating with the upper portion of the drum and also with the exterior of the brooder, and a water pan held on the top of the drum, the inclosing casing of the drum being provided with Ventilating means.

3.. A brooder comprising an inclosing casing having a heating drum therein, pipes radially extending into the upper part of the drum and communicating with the exterior of the casing, a circular pipe also having one terminal entering the top of the drum and the opposite terminal communicating with the exterior of the casing, and a water panlon the top of the drum.

4l. A brooder comprising an inclosing casing having a heatingdrum therein, pipes radially extending into the upper part of the the supplemental bottom and slide, a drum drum and communicating with the interior of the casing, a circular pipe also having one terminal entering the top of the drum and the opposite terminal communicating with the exterior of the casing, a water pan on the top of the drum, and a shield surrounding the drum.

5. A brooder comprising an inclosing casing having openings lin the front andvrear sides provided with transparent closing slides, ledges at the front and rearof the casing adjacent to the said openings, the bottom of the casing having an opening through the center thereof, a drum extending upn wardly into the casing and communicating with the said opening in the bottom, a heat generating means below the drum, pipes communicating with the interior of the upper part of the drum and the exterior ofthe casing, a portion of the -pipes being radially arn ranged and the remaining part circularly disposed, and a shield, surrounding the drum,

the upper part of the casing having ventilating openings.

In testimony whereof, I affix my signature in presence of two witnesses.
